JPG To PDF API

By default, we scale your JPG to fit within the PDF page dimensions (e.g., A4, Letter) while preserving the original aspect ratio. That means:

• A portrait receipt (1200×1600) fits perfectly on a portrait A4 page—no cropping, no distortion.
• A landscape photo (4000×3000) is centered on a landscape-oriented page—white margins top/bottom, but the whole image is visible.
• Set preserve_aspect_ratio: false if you want to stretch the image to fill the page (not recommended for text-heavy content).

You'll never get a "tiny doc floating in white space" or "half the content cut off" unless you explicitly override the defaults.

No. We use compression: "balanced" by default, which is tuned for documents that mix photos and text. Here's what happens:

• Receipts/invoices (text-heavy): JPEG quality is set high enough (85–90) to keep small print legible. File size shrinks ~38% vs. the original JPG.
• Camera photos (color-rich): We apply more aggressive compression (~70–80 quality) because photos tolerate lossy compression better. File size drops 50–72%.
• Need pixel-perfect fidelity? Set compression: "lossless" to embed the JPG as-is (larger file, zero quality loss).
• Need smallest possible file? Set compression: "maximum" (quality ~60–70)—good for thumbnails, not recommended for archival docs.

We've processed 214M+ images. The default "balanced" mode works for 99% of use cases—text stays readable, file size stays reasonable.

Yes. Send an array of input_urls:

{
  "input_urls": [
    "https://files.example.com/page1.jpg",
    "https://files.example.com/page2.jpg",
    "https://files.example.com/page3.jpg"
  ],
  "options": {
    "fit_to_page": "A4",
    "compression": "balanced"
  }
}

You'll get one PDF with 3 pages, in order. Perfect for multi-page receipts, scanned forms, or batched uploads.

We auto-rotate based on EXIF orientation data. If the camera saved "this photo was taken in portrait mode" in the metadata, we'll rotate it before embedding in the PDF—so users never see sideways receipts.

If the JPG has no EXIF data (common with screenshots or web images), we assume "upright" orientation. You can override with rotation_degrees: 90 if needed.

Median conversion time is 420ms for typical receipts/photos (1–3MB JPGs). Large camera photos (8–12MB) might take 800ms–1.2s.

We scale horizontally—bursts of 1,000 concurrent conversions are fine. Your bottleneck will be network I/O (downloading the JPG from your storage), not our processing time.

For ultra-low-latency UX, use async webhooks: POST the job, return immediately, we'll webhook you when the PDF is ready (~420ms later).

Yes. We support all JPEG variants: .jpg, .jpeg, .jfif, progressive JPEGs, and CMYK color space. The API detects the format automatically—you don't need to specify it.
